simplify log_{1/7}(1/49)

Solution

simplify

lo g_{\frac{1}{7}} (\frac{1}{49})

Solution

2

Solution steps

lo g_{\frac{1}{7}} (\frac{1}{49})

Apply log rule:

lo g_{\frac{1}{a}} (x) = - lo g_{a} (x)

lo g_{\frac{1}{7}} (\frac{1}{49}) = - lo g_{7} (\frac{1}{49})

= - lo g_{7} (\frac{1}{49})

\frac{1}{49} = 7^{- 2}

= - lo g_{7} (7^{- 2})

Apply log rule:

lo g_{a} (a^{b}) = b

lo g_{7} (7^{- 2}) = - 2

= - (- 2)

Apply rule:

- (- a) = a

- (- 2) = 2

= 2
